The adapter for the EGS valve should be removed
periodically to inspect the o-ring and to make cleaning of
the side block interior easier. Note the stud which is used to
mount the side block is fastened with Loctite
®
222. This is a
dealer serviceable item only.
7.6.2 Cleaning and Lubricating
1) Clean all the metal first in the soapy water solution
and then in a
50/50
dilute solution of white vinegar/
water. Rinse in fresh water.
2) Check the Teflon
®
seat for wear and/or contami
-
nation, and replace if necessary. Damage such as
a rough face or cuts to the seat indicate it must be
replaced.
3) The Teflon
®
washer and o-ring must be replaced
if worn.
4) Be sure to place a light coating of lubricant on all
internal moving parts, o-rings, and washers. How
-
ever, do not lubricate the Teflon
®
seat, as this will
attract dust and debris.
All internal moving parts (with the exception of the valve
seat) and o-rings should be regularly lubricated.
